To all whom it may concern:

Be it known that I, J Ace]: Scnwmznn, a citizen of the Republic ofSwitzerland, residing at Solothurn, in Switzerland, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of the specification, and in which Figure 1 is a vertical sectional view of my improved burner. Fig. 2 is a top view of the same. Fig. 3 is a transverse sectional view on line M N, Fig. 1. Fig. 4 is a similar view on line I? Q, Fig. 1. Fig. 5 is a sectional viewof a group of burners having a common supplypipe. Fig. 6 is a plan view of the same. Fig. 7 isa side view of a modified form of the burner. Fig. 8 is a vertical transverse sectional View of the same. Fig. 9 is a plan view of a group of the said modified form of burners, showing them provided with a common supply-pipe. Fig. 10 is an end view of the same, and Fig. 11 is asectional view of a regulating and stop cock for the burner.

Similar letters of reference indicate corre sponding parts in all the figures.

My invention has relation to burners for hydrocarbons, and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the'accompanying drawings, the letter A indicates a tank or receptacle for containing the hydrocarbon under pressure, a pipe, 0, extending from the said tank and conveying the hydrocarbon from the tank to the burner This burner consists of a rounded cap, I1], secured at its edge to a plate or bottom piece, F, forming an arched chamber, a, into which the upper end of the feed-pipe opens, the said pipe having its bore i provided with a stop and regulating cock, 0. This bottom piece is provided with a dow nwardl y-extendin g flange, G, which is provided with a row of holes or perforations, a. To the lower portion of this flange is secured a heavy bottom, H, which is formed with a central upwardly-tapering perforation,c, and has the feed-pipe passing through it, and another pipe, d, the upper end of which pipe passes from the arched chamber through the said bottom diametrically opposite to the feed-pipe. .Thelower end of this pipe is curved toward the central aperture and curved upward, forming a nozzle, d", which is concentric with the tapering aperture, and is located slightly below the same.

It Will now be seen that if the upperarched vaporizingehamber is heated by any suitable means, and the hydrocarbon is let into the same through the feed-pipe, it will be vaporized, and in passing out through the nozzle of the curved pipe it will carry a quantity of atmospheric air with it through the tapering ap erture into the mixing-chamber I), whence it will pass out through the apertures a and be ignited, the heat from the flames thus pro duced being sufficient to keep the vaporizingchamber hot, 'and to thus continue the production of mixed hydrocarbon vapor and atmospheric air.

The supply of hydrocarbon may be regulated by means of the cock upon the supply-pipe, and the character of the flame may be changed by mixing more or less atmospheric air with the hydrocarbon vapor, the nozzle and curved pipe being lowered for drawing a greater quantity of air with the jet of vapor, while the rais ing of the pipe and nozzle will cause the vaporjct to carry a less quantity of air with it. As the curved pipe (I is not rigidly secured in the apertures through the pieces H and F, and is preferably enlarged where it passes through either one or both of them, it can be readily moved up or down by the means of or with a slight blow from a hammer.

The stop and regulating cock is preferably constructed as shown in Fig. 11, the body C" having a transverse bore, i, formed with a seat, 0, for the plug 0' of the cock, and at each side of this seat oblique channels (I and 1' extend to the axial bore of the cock, the conical end of the plug allowing gradually-increasing volumes of fluid to pass through the cock as it is screwed away from the seat.

In Figs. 5 and 6 the burners are shown arranged at the sides of longitudinal channels C or distributingpipes, which receive the supply from the reservoir through a common sup- 2 casual .ply-pipe, this arrangement being especially suitable for furnaces for boilers or similar furnaces.

In Figs. 7 and 8 the vaporizing'chamber a is cylindrical and horizontal, and a flange, G, extends its entire length, and is formed with the outlet-apertures 02, similar to the apertures in the circular chamber, and also with the bottom piece formed integral therewith, which is provided with a number of apertures, e. The nozzles d, which register with these apertures, are formed upon the upper side of y a horizontal supply-pipe, D, which extends from one end of the vaporizing-chamber, while the other end of the chamber'has the supply-pipe Genteringit from the reservoir. I p

As shown in Figs. 9 and 10, these long groupburners, which are lettered B, may be arranged longitudinally in a furnace and be supplied from a common supply-pipe, G, a number of the long burners being secured parallel to each other.

It will be seen that these forms of burners are simple and durable of construction and not liable to be obstructed or clogged, as hydrocarbon-burners are liable to be by impurities in the fluid, and if the burner should become having a downwardly-projecting flange, said flange being provided with apertures, a heavy bottom piece secured to the lower portion of said flange, having a central upwardly-tapering aperture, two pipes through said bottom pieces, one of which is the feed-pipe and the other one has its lower end curved upwardly and provided with a nozzle, and means, substantially as described, for furnishing and controlling a supply of oil to the feed-pipe.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 28th day of October, 1886.
